Live Broadcast Audio Plan
The program adopted a "1+N" simultaneous live broadcast model, linking the main venue with multiple external locations. The technical plan included the following:
Main Studio Audio System
The HR-32D dual-channel ultra-wideband digital control intelligent wireless microphone system was used, paired with the R-14D antenna distributor, R-32AU wideband directional antenna, and PM-320 wireless in-ear monitoring system to establish a complete audio transmission chain.
Microphone Setup for Hosts and Guests
The hosts and guests utilized Relacart LM-C550 lavalier microphones. Audio was transmitted through the HR-32D system using the Dante protocol to the audio console, then monitored via the in-ear system before being sent to the live broadcast platform.
Real-Time Monitoring by the Director
The director used the HR-32D microphone system and PM-320 in-ear monitoring system to communicate with hosts and guests in real time, allowing adjustments to content and delivery for a seamless broadcast.
System Features
1. Microphone System
